TEMPERATUREREGULATING MEANS.

Application filed May 8,

To @ZZ/nimm it may concern.' y

Be it known that l, KnNNnnr DoUcAN, a. citizen olf the United Sta-tes, residing at All/linneapolis, in the county ol" Hennepin/and State of Minnesota, have invented certain new and useful Improvements in Temperature-Regulating Means, ot-which Jhe followinn is a specification.

My invention relates to means tor regulating the heating effect of Vsteam radiators or other containers in which heating fluid is contined, the heat being radiated through t-he walls of the container, and the object of my invention is,--

To provide means for increasing or decreasing the amount ot heating surface to theamount necessary to give the required heat: l attain this object by the mechanism illustrated in the accompanying` drawing, in which,

Fig. 1 is a vertical central section through a steam container with my heat regulating means shown attached thereto, also shown in y vertical section with someot the parts shown in full lines.

Fig. 2 is a similar section, enlarged, with portions broken away.

fi a central vertical section partly in full lines, ot parts shown in Fig. 2.

Fig. 4; is a horizontal section taken on the line A, Fig. 2.

Fig. 5 shows a slightly modified form of the device applied to an ordinary steam radiator such as is commonly used Jfor house warming purposes, the radiator being shown in elevation and the heat regulating device lpartly in vertical section,.and partly in full lines.

Similar numerals refer to similar parts throughout theV several views.

rlhc drawing is largely diagrammatic. 1 is a c vliudrically'shaped steam container in which steam is carried at boiler pressure; 2, the pipe which carries the steam trom the boiler to said steam container: 3 and 4t. pipes which connect the upper and lower ends ot said steam container with the upper and lower ends respectively of a comparatively small cylinder 5, and it is in this cylinder that the temperature controlling means is located and consists oit a plurality of pipes of different heights having their upper ends open and their lower ends adapted to be selectively opened and maintained open one at a time. The heating eli'ect is regulated by the amount ot heating surface in use i919." serial No. 295,766.

and this by the portion ot' the steam container that is allowed to fill with water from theboiler or with condensed steam.

6 is a cylinder formed integral with' cylinder '5 but separated therefrom by partition 7 8, a pipe conducting the water of condensation back to the boiler; 9 is a round rod having its lower end screw-threaded into partition 7 as shown, its upper end extending through a stutling box at the upper end otl cylinder 5 as shown, 11 being a stu'liing box screwed into the upper end of cylinder 5; 12, a gland screw threaded into stuiiing box 11; 13, the packing; 14C, a hand wheel secured to-rod 9.

.ln order that conduit 19 may be caused to register with any one ot conduits Q0, 21, Q2 or 9?), hand wheel 14 hasI tour graduation marks on its periphery which marks are equi-distant apart and numbered from 1 to 4i inclusive,'only two ot these marks, 1 and are shown. Slidably mounted upon cylinder 5 in brackets 2G and Q6 is an indicator 27 provided with a linger piece 28 by which to move it up or down to bring its upper end close to wheel 14. When one of the graduation marks 1 to t on hand wheel 14 registers with an indicator mark (not shown) on the upper surface ot indicator 27, its corresponding' conduit is in register' with conduit 19. Fitting snugly upon the unthreaded portion ot rod 9 and supported by a collar 15 formed integral with or rigidly secured to said rod 9, is an annulus 16 provided on its periphery with a projection 17 adapted to reciprocate in a groove 18 formed in cylinder 5. Projection 17 prevents rotation ot annulus 1G but permits it to be moved up or down by the means provided. which consists ot the screw-threaded portion ot rod 9 rotating in partit-ion 7, whico is also screw-threaded, and which rod 9 is adapted to be rotated manually by means ot hand wheel 14- which is rigidly secured to rod 9, the purpose ot which is to raise or lower annulus 16 and with it the pipes 21, aud Q3 as well as the annulus itself in which hole Q9 is formed. Rod 9 is a snug Ht in annulus 1G in order to prevent the pas` sage ot water between said annulus and said rod but not sufliciently tight to prevent turning by the means provided. Formed in the lower portion ot rod 9 is a central vertical conduit 19. not shown in Fig. 1 but clearly shown in Fig. 3 and in dotted lines in Fig. 2. Conduit 19 turns in a horizontal directively with any of the four conduits 20, 21,

Y22 an-d 23, shown in Fig. 4, conduit 2O being vmay flow from above partition Vshown also in Fig. 3. It will be noted that Ythere is but one conduit in rod 9, and that by rotating hand wheel 14rod 9 can be rotated to bring conduit 19V into register with any one of conduits 20, 21, 22 orV 23. It is Yj obvious that when one of said conduits is in register with conduit 19 that thereV willV be-an'open passageway from the upper toA the lower side of partition 7 and that water 7 down through conduit 19 and out through conduit 8 Vand back to the boiler. Y

AThe operation is as follows:

When the entire heating effect of the steam container is` required conduit; 19 is brought into register with conduit 2O the upper Vsurface of which level with theY upper surface of annulus 16 in which saidV conduit 2O is formed; water will now drain out of steam container 1 downto a level with the upper surface of annulus 16. If any of the other pipes be brought into reg-v ister with conduit 19 water, that is to say condensed steam, will accumulate in said steam container until it rises above the upper endV of said pipe when it will flow out through conduit 19 and prevent the further rise of water in said steam container and in this way maintain a uniform amount `of heating surface. Y

Any portion of the heating surface may be utilized, as by rotating hand wheelV 14 the pipes 21, 22 and 23 as well as conduit 29' may be raised or lowered, to cause the waterl to overflow at any desired height, within the elevationdue to one rotation of hand wheelV 14, by which is meant thatvsince conduit 19 must always be stopped when in Vis not threadedvbut is Vadapted to rotatein Vannulus 16 and. is' raised orlowered by Vmeans of hand wheel 14 which is rigidly fsecured to the upper end* of said rod 9. 29

is a support'rigidly secured to cylinder 5 the threadand provides means forcarrying ed -upper end ofirod 9. ,Y

I claim;

In a deviceof the kind described, a steam container, a hollow vertical vcylinder closedV at both ends, a partition across said cylinder between its ends, a steam connection between the lower end of said' steanrcontainer and said vertical cylinder above said partition,

and a steam connection between the' upper Y end of said steam container and the upper end of saidvertical cylinder, a rod extending through a portionyof said vertical Cylinder and through said partition, a conduit formed in said rod, leadingfrom its exterior, to its interior and from above to below said partition, and discharging intosaid vertical cylinder, an annulus carried by sai-d rod above said partition, a plurality of vertical conduits of variable heights carried by said annulus, means for bringing the aforesaid conduit in said rod into register with any4 of the aforementioned vertical conduits of variable heights carried by said annulus, and means for reciprocating/said annulus in said cylinder, V

In testimony whereof I vailix my signature.
